Dear list, I have this sample: \setupinteraction[state=start] \starttext \def\cB{file.pdf} \def\cC{file with spaces.pdf} %~ \def\PathName{\cldcontext{[[\env{completepath}]]}} \def\PathName{% \cldcontext{string.gsub([[\env{completepath}]], "\\\\", "/")}} no spaces: \doifelsefileexists{\PathName\cB}{yes}{no} \attachment[file={\PathName\cB}]\\ with spaces: \doifelsefileexists{\PathName\cC}{yes}{no} \attachment[file={\PathName\cC}] \stoptext It works fine in Linux with spaces in file names. I invoke it with: context --purgeall --arguments="pathname={~/}" ~/a But in Windows, the actual invocation involves a loop in a batch file. Without the loop, it would read (for drag and drop): context --purgeall --arguments="completepath=%~dp1" file-above.tex I don’t get the attachment only with the file that has spaces in its name (the file is also reported as not existing). The file without spaces in the its name is being attached and reported as existing. Does anyone know what might be preventing ConTeXt in Windows not to recognize the existing file with spaces in its name? Many thanks for your help, Pablo -- http://www.ousia.tk
